if you could go back 100, 200, maybe FIVE HUNDRED YEARS in time, what music would you play them? who would you like to play for? and what do you think they'd think about it? i can just imagine playing some coltrane or some yes or some flecktones for some of the monks that came up with neumation, or or for bach or haydn and say: hey guys, because of you there's stuff like this! and then watch them freak out.
